摘要
目的分析不同病理分型小儿急性阑尾炎的高频声像图和彩色多普勒血流特征并评价其诊断价值。方法回顾性分析102例经手术病理或临床证实的急性阑尾炎患儿应用高频彩色多普勒超声诊断。结果小儿急性阑尾炎超声诊断符合率97.06%,各型阑尾炎诊断符合率相似。声像图特征:单纯性及化脓性阑尾炎显示不同程度阑尾增粗,壁增厚,黏膜回声中断、毛糙或缺失;坏疽性阑尾炎阑尾结构紊乱,壁层次不清或中断;各型阑尾炎阑尾血流分别呈丰富、中等、稀疏、消失四级。结论高频彩色多普勒超声诊断不同分型小儿急性阑尾炎有较高实用价值,诊断应以高频声像图为基础,结合彩色多普勒血流丰富程度分析。
Objective To explore the characteristics of children’s acute appendicitis with different pathological classification on high frequency ultrasonography and color Doppler flow imaging (CDFI) and to evaluate their diagnostic value.Methods A total of 102 children proved to be with acute appendicitis by operation and pathology were analyzed respectively and diagnosed with high frequency color Doppler ultrasonography.Results The diagnostic accuracy rate of ultrasonography was 97.06% and there was no significance in different types.The diameter and wall of appendixes were thickened and the mucous membranes were coarse with echoes interrupted or absent in simple appendicitis and purulent appendicitis to different degrees.The structures of appendixes were inordinate and the wall of appendixes was thickened or interrupted in gangrenous appendicitis.CDFI showed different signal grades including absent,sparse,moderate and abundant in appendixes with different types of appendicitis.Conclusions Ultrasonography is of high value for diagnosis and classification of appendicitis in children.The diagnosis standard must depend on the high frequency ultrasonography and the combination with the density of the flow signals on CDFI.
